How many watts on a 40 amp circuit breaker?
about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)
Can a 220V x 40W bulb bought in India used in America where supply standard is 110V x 60Hz and does the power consumed varies?
If you can use it in your lamp it will be a 20 watt bulb
How many amp hours does a 23 watt bulb use?
The formula for finding amperage is I = W/E. Amps = Watts/Volts. Without the value of the voltage to the bulb this question can not be answered.
How do you find kva?
k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA
Which kind a light bulb uses the least amount of energy a fluorescent lamp a halogen lamp a incandescent lamp or a heating lamp?
Fluorescent lights use far less energy than any of the others listed.
How do you use the word dimmer in a sentence?
A 40 watt bulb is dimmer than a 100 watt bulb.
What is the efficiency of a filament bulb that produces 100 j and a fluorescent bulb that prduces 10 j?
Any bulb can produce 10 J or 100 J depending on how long it is left switched on. A 100 w bulb consumes 100 joules of energy each second, while a 10 w bulb needs to run for 10 seconds to use 100 joules. An incandescent bulb produces about 10 lumens per watt, A halogen bulb produces 13 lumens per watt, Compact fluorescent bulbs and LEDs produce 50-60 lumens per watt.
Do you go by watt equivalent or actual watt usage on a halogen bulb to determine what bulb to use?
Strictly the power in watts measures how much energy is used, while the brightness is measured in lumens. Bulb packaging should carry that information. But 'equivalents' are a useful way for manufacturers to bamboozle customers, so halogens often carry an 'equivalent wattage' figure, which means the power of an ordinary old incandescent bulb of the same brightness. If you had a 100 watt old-fashioned bulb, that is replaced by a 70 watt halogen. It could also be replace by a 20 watt CFL bulb that is obviously less expensive to run and lasts much longer.
How much more money will it cost if you use 100 watt bulb then a 60 watt bulb?
Almost twice as much as 100 is almost twice 60.
Do 100-watt light bulb use energy 4 times as fast as does a 25-watt bulb?
Yes, that is what the numbers mean.
Can you use a 300 watt 220-240 watts halogen bulb on 240 watt mains?
Nobody has "240 watt mains". Perhaps you meant "240-volt mains".You would need to have a lighting or receptacle branch circuit, with over-current protection, in order to use any halogen bulb.However, if you have a 300 W bulb, it should work nicely in a 15-A or 20-A branch circuit.
How much energy does a nightlight use compared to a 100 watt bulb?
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
Can you use a 120 watt equivalent 80 watt actual usage in a 100 watt reptile light fixture?
A reptile light is used to generate heat for the reptile, so you must use a bulb that uses 100 watts, and an incandescent bulb is what you need.
How many milliamps does a 100 watt bulb use?
To answer this question a voltage is needed.
Can you use a 100 watt light energy saving bulb in an old fashion light fixture that only allows 60 watt bulbs. The energy saving bulb says it only actually uses 23 watts.?
Different technologies produce different amounts of light - measured in lumens - for a given amount of electric power - measured in watts. Incandescent: 12 lumens per watt Halogen: 16 lumens per watt CFLs: 50-60 lumens per watt LEDs: 100-120 lumens per watt
Which would use more energy a 50 watt bulb or a 75 watt bulb?
A 75 bulb will use more electricity.
Are halogen bulbs more energy efficient than traditional incandescent bulbs?
Well, if they're both 40 watt bulbs they use the same amount of electricity. But incandescent bulbs produce a lot of heat as well as light. Fluorescent bulbs don't produce (much) heat, so they can use their power to produce light. So you can use fluorescent bulbs of lower wattage to produce the same amount of light.So for the same amount of light, fluorescent bulbs use less electricity than incandescent bulbs.
